Ok. I'll try to provide as much information as I can.
- Wired or wireless doesn't change anything. I have tried both.
- I'm using a DSL connection with a WPA2 encryption
- No proxi, DHCP

Mr. Willstrand asked me to do the following:

[simon at sangam ~]$ nslookup download.fedoraproject.org
Server:                192.168.1.1
Address:        192.168.1.1#53

Non-authoritative answer:
download.fedoraproject.org        canonical name = wildcard.fedoraproject.org.
Name:        wildcard.fedoraproject.org
Address: 66.35.62.166
Name:        wildcard.fedoraproject.org
Address: 80.239.156.215
Name:        wildcard.fedoraproject.org
Address: 152.46.7.222

And if I directly type "firefox 66.35.62.166", I get to  
http://fedoraproject.org/wiki/IndexAdmin without further problem. So  
he means that this might be a problem with DNS...
